What's another lesson that David and wife Victoria Beckham try to instill in their children?

"It's important to work hard," David explained. "That's one of the key things me and my wife have always done, [both] before we had children, and now [that] we have four children."

"I've done that throughout my footballing career and I'll continue to do it outside," he said. "We juggle everything around the family because our main priority is the children, simple as that, and it always will be, but being hardworking is the best thing you can show children."
